The objects of this invention are to secure denture retaining devicessuch as lingual and palatal bars and clasps that are used in partialdentures which can be readily shaped to the contour of the patientsmouth and yet shall be stifiiy rigid as is necessary in use to 1material to complete the bar; to provide in a denture retaining device athin sheet metal portion which will readily take the shape of thepatients mouth, said sheet metal portion havingat one side wire or thelike which is 6 pliable so as to be shaped as desired and at the sametime retain such shape for itself and the sheet metal, whereby a bodyportion is secured which may be filled with or have applied theretostiff solder to complete the bar;

to thus enable bars to be readily and accurate- 1y fitted before theyare still and yet when finished to be rigid to resist bending and holdthe saddles fixedly in position, and to secure other advantages andresults as will be I brought out in the following description.

Referring to the accompanying drawings, in which like characters ofreference indicate the same parts throughout the several views,

Figure 1 shows in a plane a piece of light sheet metal such as is usedfor the body of'a lingual bar embodying my invention;

Figure 2 shows the same with a rim formed on one side thereof by spotsoldering a piece of wire thereto, thus forming the body por- 40 tion'of my improved bar;

Figure 3 shows said body portion with wax applied thereto to facilitatebending and shaping it to the contour of the model;

Figure l shows said body portion bent or shaped tothe contour of amodel, and part of the wax removed;

Figure 5 shows stiff solder or the like ap- V Figure 6 is across-section on line 66, Fig. 0.

in the specific embodiment of the invention set forth in said drawings,1 indicates a strip of thin malleable metal such as palladium or thelike, which is adapted to be bent and shaped to the mouth of the patientor a model thereof which is commonly used for the purpose. This strip 1is, for a lingual bar, preferably somewhat arcuate in its plane, as ishown in Figures 1 and 2, so that it lies horizontally in the mouthwhen-shaped, and the ends of the strip 1 are preferably apertured asshown at 2, 2 to provide. in the completed bar openings for the materialof the saddles to enter and thus secure a better attachment.

To one side of the said strip 1, while it is still in plane form, issoldered a wire 3 extending clear around the strip, near its peripheraledge, with its ends substantially meeting at a suitable point, as at l,said wire lying outside the apertures 2, This wire 3 is of suchcomposition that when applied tothe strip 1, as shown in Figure 2, thecombined strip and wire can be readily shaped to the patients mouth ormodel thereof, and when so shaped will retain such shape or form. Thebody part of my improved lingual bar, consisting of the strip 1 and wire3, forming a rim, is preferably filled with wax 5, as shown in Figures 3and 4, which is toughly yielding and helps distribute and equalize thepressure of the operators fingers in contouring the body portion to themodel. Said body portion is shown in Figure 4 as shaped to fit aparticular patient, and when it has been so shaped, the wax 5, if it hasbeen used, is melted or burned off, as by a blow torch, and the space orrecess enclosed by the rim wire 3 is filledat the inner or concave sideof the body part with stiff solder or equivalent material (5 which willgive. saidinner or convex side ofthe lingual bar a rounded orapproximately semi-cylindrical surface and suflicient body or thicknessto aflordthenecessary rigidity. Thiscompletes the bar which then appearsas shown in Figure 5, openings 2, 2 being still left in the ends of thearms of the bar, although the stiff solder or the -i plied to the bodyportion of the bar so as to 50' complete the bar, and like. may extendaround the SdIHe. The cross section of the bar appears as shown inFigure 6, the Wire 3 being embedded in the still solder (i. The stitl'solder or the like 6 is given a smoothly rounded and finished sur facemerging into the exposed side of the sheet metal strip, 1, and thus abar is provided which, cgn be utiliqed for a. partial denture in amanner similar to bars previously in use.

while Ihaveshown myinvention embodied in a lingual bar orban for a lowerdenture, it will be obvious that the invention can be similarly embodiedin a palatal bar or bar for an upper denture, or, other dentureretaining devices.

It will; be seen, that my iniproaed bar 18 very readily and convenientlymade, and imiklifiwlp Q3111 be very accurately fitted,
